Abstract

A connector is mateable with a mating connector which includes a mating contact having a mating contact point. The connector comprises a contact and a holding member which holds the contact. The contact has a contact portion. When the connector and the mating connector are mated with each other, the mating contact point slides on and is in contact with the contact portion. The contact portion has a first plated layer as its outermost layer and a second plated layer located under the first plated layer. The first plated layer is made of silver or silver alloy and has Vickers hardness not more than 90 Hv. The second plated layer is made of silver or silver alloy and has Vickers hardness not less than 100 Hv.

First claim

What is claimed is:

1. A connector joinable with a mating connector which includes a mating contact having a mating contact point, wherein:
the connector comprises a contact and a holding member which holds the contact;
the contact has a contact portion and a base member, the base member being made of copper or alloy;
when the connector and the mating connector are mated with each other, the mating contact point slides on and is in contact with the contact portion;
the contact portion has a first plated layer as its outermost layer and a second plated layer located under the first plated layer, the second plated layer being formed on the base member;
the first plated layer is made of silver or silver alloy and has Vickers hardness not more than 90 Hv; and
the second plated layer is made of silver or silver alloy and has Vickers hardness not less than 100 Hv.

2. The connector as recited in claim 1 , wherein the second plated layer contains silver of 90 wt % or more.

3. The connector as recited in claim 2 , wherein the second plated layer further contains, as a remaining part other than the silver, at least one element selected from the group consisting of Sb, Se and Te.

4. The connector as recited in claim 1 , wherein the Vickers hardness of the second plated layer is not more than 180 Hv.

5. The connector as recited in claim 1 , wherein:
when the connector and the mating connector are mated with each other, the mating contact point slides on the contact portion along a predetermined direction; and
the mating contact point has a shape which projects toward the contact portion in a direction intersecting with the predetermined direction.
